Dec. w, 1929. H. L EsslNG 13382-835 FOUNTAIN PEN Filed sept. 20. 192e Patented Dec. IO, 1929 UNITED STATS HANS LESSING, OF BERLIN-CHARLOTTENB'URG, GERMANY FOUNTAIN PEN Application led September 20, 1926, Serial No. 136,517, and in Germany September 25, i925.

This invention relates to fountain pens, and more particularly to a fountain pen, which consists of two parts inade to be rotary to eaeh other, and in which the passage of the 5 inlr from the main barrel to the front barrel carrying the nib is capable of being regulated.

According,` to the invention the adjustment or closure plate is furnished with several G openings, and is connected with the front barrel b v means ot a ring; or' soft material, whieh simultaneously acts as a washer. The said ring, which is preferably composed of soft rubber, is employed as a coupling niem- 15 ber between the iront barrel and the closure plate, the two latter parts being` for this purpose provided with projections.

The invention will now be described more 'fully with reference to the accompanying 2o drawing, in which Fig. 1 is a section through a possible 'form of embodiment of the pen.

Fig. 2 is a section on the line 22 oit Fig. 1, with the passages open, and

Fig: 3 a similar view to Fig. 2 with the passages closed.

Referring' to the drawing 10 is the main barrel, which is closed at its upper end by means ot a plate 11. This plate may consist se of One piece with the main barrel, or may also be fitted separately. On tbe upper setoii1 edge 12 of the barrel 10 is mounted the frontbarrel 13, which is capable oi' rotation. The

lirontbarrel 13 is set ofi' in the interior, i. e., 35 is furnished with an inner shoulder, and in this part is mounted the soft rubber ring 14;.

Below the rubber ring 141 is situated the olosure plate 15, which is furnished with holes 16. The closure plate 11 ot the main barrel to 10 possesses corresponding holes 17 which, as shown in Fig. 2, may be moved into alignment withthe holes 16, in order to allow the ink to pass through into the front barrel.

The inner set-oilC edge of the front barrel e5 is provided with projections 18 which, as shown in Fig. 1 project into the upper edge oit the soft rubber ring when the two barrels are set together. The edge portion on the upper `face side of the plate `15 is also fur- Sie nished with projections 18, which thrust into the lower edge of the rubber ring. The main barrel is provided on its extreme periphery with grooves 19, in which engage pins 20, which are mounted on the front barrel above the lower edge thereof.

The soft rubber ring; 14e forms a washer 'tor preventing the ink from passing outwardly after its jjiassage through the opening; provided. Due to the arrangement of the lq/troove and pin connection between the two barrels the soit rubber ring also presses the adjustment plate 15 on to the closure plate 11, so that a tight closure is also ensured at this point.

In addition, the ring constitutes the couplingr member between the main and front barrels.

Wl at 1 claim new and desire to secure by Letters Patent is:

In a 'fountain pen, a. main barrel, a front barrel capable of rotation in relation to the said iirst barrel, a elosuredise at the end ot the said first barrel, a closure plate seated within the said second barrel and resting over the said closure disc, a rubber ring washer mounted within the said seco-nd barrel pressing` the said closure plate on to the said closure disc, projections on the interior oft the said second barrel and projections on the edge of the said closure plate, the said projections serving to iirmly engage the said washer, a pluraiitv of holes in the said closure dise, and corresponding holes in the said closure plate.

In testimony whereof I have aflixed my signature.

HANS LESSNG.
